The majority of people just throw eggshells in the trash; however, they can be really useful in our everyday lives. In the following article, we’ll cover some of the most surprising uses for eggshells.

Eggshell Facts

An eggshell is composed of calcium carbonate, which is also an ingredient found in certain antacids.  The shell of a medium-sized egg contains approximately 750-800 mg of calcium.

The shell accounts for 9-12% of the total weight of the egg and has pores that allow for the exchange of oxygen and the release of moisture and carbon dioxide.

The color of the shell depends on the breed of hen that laid the egg. In other words, white hens produce eggs of the same color, and brown ones lay brown eggs.

What are some uses for eggshells?

The eggshell membrane (the slightly transparent film inside) is used to help heal cuts and scratches. So, the next time you get hurt, apply some of this film and let it do its job.

Starting seeds

If you’re starting a garden (or even a container garden) you can add eggshells to the soil, just like with tomatoes. Mix some eggshells along with some compost or fertilizer into your soil. You can also scatter them on top of the soil of your garden and flowers or add them to a compost pile.

Place the shell, as complete as possible, in the freezer and use it to clean and sharpen the blades of your blender. Just add water and run the blender.
